Chief Henry Oscar One bull, a Hunkpapa Sioux, was a nephew, adopted son and bodyguard of the famed Chief Sitting Bull. When Major Marcus A. Reno attacked the Indian village early in the Battle of Little Big Horn, One Bull was ordered by Sitting bull to parley with the soldiers if he could. When the soldiers kept attacking, One Bull led a counterattack, killing three soldiers. He died in 1947, aged 94
“The night before the Long Hair Fight, Sitting Bull went to the ridge where the monument now stands. He offered up a prayer, asking Wakan Tanka (God) to guard his people against danger and misfortune.” – Crow Fair, SD 1938
